As above stated, the machine herein shown and described for the purpose of illustrating a preferred embodiment of the present invention, is a machine of the type disclosed in my said co-pending application. Conveniently, and as shown, except as hereinafter fully explained. and described in detail, the machine may be constructed like or substantially like the machine illustrated in said co-pending application, and refer-- ence should be had to the specification and drawings of said co-pending application for detailed exposition of features and details of construction and operation not fully explained and described herein.

The illustrated machine, as hcreinbefore stated, is designed to permit the presel'itation thereto of work provided with a plurality of buttons and buttonholes and to perform thereon during one operation of the machine and substantially simultaneo'usly, a plurality of buttoning operations, the operation of completely buttoning a single button being usually herein termed a buttoning operation. For buttoning each button, the illustrated machine has a set of operating instrumentalities comprising work receiving means and means for taking the work from the receiving means and performing a buttoning operation. As shown, the machine has seven such sets of operating instrumentalities, although obviously the number of sets may be greater or less as desired, the illustrated machine being equipped with the above stated number of sets because, in practice, seven buttons is usually the greatest number which it is desired to button on a single upper.

For receiving the work from the operator and presenting it to the buttoning instrumentalities, the machine is provided with a series of horizontally disposed button receiving and positioning forks 2, (Fig. 1) commonly herein termed button holders, and a series of buttonhole fly receiving members, usually herein termed fly holders, comprising a plurality of horizontally disposed forks 4 positioned above the button receiving forks 2 and having associated therewith a corresponding number of buttonhole Spreaders 6. To prevent catching in the outer or end buttonholes of the series of buttonholes to be operated upon during the introduction of the work into the fly holders, each of the outer forks 4, as shown, has only one prong (Fig. 1), the outer members 4; being nevertheless for convenience generally herein referred to as forks as well as the intermediate and forked members 4.

Each of the butt n r ce i g ks 2 prises a pair of arms 8 and 10 forming an open mouthed slot 12. As shown, the two outer button receiving forks 2 are each provided with a pair of spring fingers 1 1, best shown .in Fig. 10, formed to allow the eyes of the two outer buttons of the series of buttons to be operated upon to be passed inwardly between and beyond the adjacent portions of said fingers and to retain said button eyes yieldingly against accidental displacement of said buttons from the end button forks, thus holding the series of but tons as a whole from becoming accidentally dislodged from the button receiving forks. Conveniently, the spring fingers 1% may be formed of wire bent, for example, as shown in Fig. 10, the rear ones of the wire fingers 14: being received in grooves channeled in the top faces of tie plates 16 pinned to the under sides of the end button forks 2. Preferably, too, the arms 8 and 10 of the button receiving forks 2 are beveled around their inner faces as shown at 18 (Fig. 10) to prevent cutting or fraying the button attaching threads as the buttons are introduced into the button receiving forks. Advantageously, also, and as shown, the spring fingers 141 carried by the end forks 2 may be beveled on their under sidesat and near their front ends as indicated at 20 and the under faces of the front ends of the arms of the several forks 2 may be similarly beveled, as indicated at 22, (Fig. 10) to facilitates straightening the buttons into upright position as they are introduced into the button receiving forks.

In the use of the above-described button receiving forks 2, the eyes of the buttons are received in and stand in the slots 12, the buttons being held upright in the said forks by reason of the flat bottoms of the button heads resting upon the upper faces of the arms 8 and 10 of the forks 2, (Fig. 3) and the eyes of the end buttons being forced between the spring fingers 14 and held yieldingly by those fingers against accidental movement from said end forks.

Each of the button forks 2 is carried at the front end of a slide bar 24:, the slide bars 24 passing through and being supported in guides 26 (see Figs. 2 and 11) and secured at their rear ends for reciprocating movement with a slide 28 (Fig. 2) traveling on shelves 11 (Fig. 2) projecting from the side walls of the machine frame and arranged to be operated to reciprocate the slide bars 24 and button holders 2 by a cam 29 on the main shaft 30 tllrough a link 31 and a lever 32 fulcrumed on a cross shaft 33 supported by the machine frame. said lever 32 carrying a roll 34 for engaging said cam 29.

To adapt the machine especially for receiving and properly positioning buttons attached in such a manner that the buttons are presented to the button receiving forks 2 with the eyes of the buttons extending crosswise of the positioning slots formed by the arms of said forks, whenever it is desired to operate upon buttons so attached, the button receiving forks 2 may be constructed and arranged, as shown in Fig. 23, wherein each of the button receiving forks 2 is shown with the inside face of its outer arm curved to provide a cam face 36 and shaped at its mouth to be wide enough to receive a button presented with its eye extending transversely of the fork, the cam face 36 operating to turn the button as it is moved into the fork to direct the eye of the button lengthwise of the fork in position to be received in the relatively narrow portion of the slot 12 for presentation to the buttoning means.

The buttonhole fly holders 1, as illustrated, are mounted and operated in substantially the same manner as the button receiving forks 2, the fly holders 1 being formed on the front ends of slide bars 38 which pass through and are supported in the guides 26 (Figs. 2 and 11), each buttonhole fly holder slide bar 38 resting upon a corresponding button holder slide bar 2 1. The rear ends of the slide bars 38 are operatively connected for horizontal reciprocating movement with a slide -10 guided at its ends between shelves 25 and brackets 27 t (Fig. 13) secured to the side walls of the machine frame and connected by a link 42 with a lever 13 fulcrumed on the shaft 33 and carrying a roll 14 engaging a cam 45 on the main shaft 30.

The buttonhole spreaders 6 for each set comprise a pair of horizontally disposed spreader arms +16 (Fig. 12) located below the buttonhole fiy supporting forks 4 and pivoted for opening and closing movement at 17 in a shell -18. Each shell 18 is pivotally connected at to the corresponding fly holder slide bar 38 for movement with the associated fly holder 4- lengthwise of the machine. Each spreader arm 46 carries at its front end an upstanding blade 52 adapted to enter a buttonhole. To maintain the spreader arms 16 and the spreader blades 52 normall togethcii' in the closed position of the spreader-s, springs at (Fig. 12) are disposed between the rear ends of the spreader arms of each set.

In the use of the machine, the buttonhole fly is initially positioned so that it rests upon and is supported by the buttonhole fly receiving forks 1: and the spreader blades 52 project upwardly through the buttonholes (Fig.

For convenience in introducing the work, the fly holders 1 and spreaders 6 in their initial positions project forwardly away from the machine in front of the buttoning means, as shown, for example, in Figs. 1 and 2, the term work for convenience being variously used in this specification and the appended claims in a broad sense to designate whatever is handled or operated upon by any of the instrumentalities of the machine such, for example, as the upper as a whole, the buttonhole fly or button piece, or both, or the buttons attached to the upper. Similarly, the outer ends of the button receiving forks 2 are normally substantially in line with the buttonhole fly holders 4, as clearly shown, for example, in Fig. 2.

During the first part of the operation of the machine, the fly holders f and spreaders 6 are moved backwardly toward the machine to position the buttonholes for the action of the buttoning means (Fig. i), the spreader blades 52 preventing accidental disengagement of the fly from the fly holders during this movement. During this backward movement of the fly holders l, the spreader arms a6 are forced apart by sliding engagement with projections 53 on the shanks of the button holders 2 and normally standing in slots 55 (Fig. 12) formed by recesses in the adjacent faces of the two spreader arms 46 of each pair. This causes the spreader blades 52 to act upon opposite sides of each of the buttonholes to spread the buttonholes and hold them open to facilitate the entrance therein of the button head engaging means.

For swinging the shells d8 about their pivots 50 to lower the spreaders out of the buttonholes after the buttonholes have been entered by the button head engaging means and thus positioned for the-buttoning operations, the shells 4-8 are provided with ex tensions 56 adapted to ride over inclined faces 58 on the button holder slide bars 24. The construction is such that, after the buttonholes have been presented to and entered by the button head engaging means, the fiy holder slide bars 38 are given a backward movement while the button holder slide bars 2t-remain stationary with the result that the extensions 56 on the shells 48 are caused to ride upwardly over the inclined faces 58 on the slide bars 24: against the resistance of spring pressed plungers 60 engaging the shells 48, thus tipping the shells 48 in a direction to lower the spreaders from the buttonholes, continued backward movement of the fly holder slide bars 38 carrying the fly holders 4 and spreaders 6 into an inoperative position shown in Fig. 5.

As above stated, in addition to the work receiving means each set includes means for taking the work from the receiving means and performing a buttoning operation. For

taking the work from the receiving means and positioning the buttons and buttonholes for the buttoning operations, each set has a vertically disposed button head engaging plunger 62 and an opposed cooperating but ton eye supporting anvil 64, the said plunger and the said anvil being arranged for movemennt into position to hold a button between them upon presentation of the button by the work receiving means.

Each plunger 62 comprises a work ongaging portion 65 (Fig. 16) and a stem 66 adjustably supported in a sleeve 68 by means of an adjusting nut 70, the adjusting nut 70 of each set having threaded through it a tapered pin H l6 and 17) for the reception of which the upper end of the corresponding plunger stem 66 is drilled and split as shown in Fig. 17. The tapered pins 74% expand the tops 75 of the plunger stems 66 by wedging engagement therewith and securely lock the plunger stems in adjusted positions in the sleeves 68. Each plunger 62 is spring pressed toward the work by a rather still coil spring 76 (Fig. 16) seated between a shoulder 78 on the plunger 2 and a shoulder 80 on the inside face of the sleeve 68. The button head engaging faces 81. of the plungers 62 are preferably cupped, as indicated in Fig. 16, to cause each of them to conform approximately to the contour of the crown of a button head and, to provide for operating for example, upon buttons of the type illustrated in Fig. 22, the cupped ends of the plungers 62 have central recesses 83 (Fig. 16) adapted for the reception of the projecting portions 85 of the said buttons. As shown in Fig. 21, the work engaging end face 81 of each plunger 62 may be bored lengthwise of the plunger to receive a plug 82 slidably secured to the plunger by a headed rod 8 1- and normally pressed outwardly by a spring 86, each plug 82 normally projecting slightly beyond the plunger end and yielding upon engagement with the head of a button as much as may be necessary to cause the plunger to conform to the shape of the crown of the button head.

The plunger carrying sleeves 68 are supported in holders (Figs. 1 and 2) by means of the nuts 72 which are threaded on the sleeves 68 at their upper ends and rest upon the upper faces of the holders 90. The sleeve holders 90 are mounted for movement with a reciprocating head 92 guided on vertical ways on the machine frame and arranged to be operated to lower and raise the plungers 62 and associated parts toward and from the work by means of a bell crank, in dicated generally at 94 (Fig. 2), fulcrumed on a shaft 96 supported by the machine frame, the bell crank 94: having two forwardly extending arms, one of which is shown at 93 (F ig. 2). slidably pivoted at to each end of the head 92, and a rearwardly extending arm 98 carrying a roll 99 arranged to engage a cam 100 on the main shaft 30.

Th an ils 64: pass up tandin bla s having flat top work engaging faces preferably roughened or corrugated as shown in Fig. 1 to facilitate firm engagement with the work, each anvil 64 being in vertical alinement with the corresponding plunger 62. The anvils 64 are adjustably secured to the front ends of bars 102 by screws 103 (Fig. 8) received in slots 105 (Figs. 1 and 8) in the front ends of the bars 102, this construction providing for adjustment of the anvils lengthwise of the machine to vary the line or curve of the anvils according to the line or curve of the buttons and buttonholes. Each of the anvil bars 102 extends through the lower part of one of the guides 26 (Figs, 2 and 11). At its rear end each anvil bar 102 engages a cross rod 104 (Figs. 2 and 13) supported at its ends for turning movement in the machine frame. To per mit the anvil bars 102 to be readily removed from the machine and at the same time to provide for locking them in the machine when in use, the cross rod 104 has two opposite flattened sides and each-of the anvil bars 102 is split at its rear end and provided with a slot (Fig. 2) adapted to receive the cross rod 104 in one position thereof and so shaped that when the cross rod is turned in the slots in the anvil bars into the position shown'in Fig. 2, each anvil bar 102 is securely locked in engagement with said cross rod.

To provide for turning the rod 104 to unlock the anvil bars 102 to permit one or more of them to be removed from the machine as desired and at the same time to provide for securing the rod 104 in position to lock the anvil bars 102 in the machine, the said rod 104 extends at its ends outwardly beyond the outer faces of the side walls of the machine frame and is provided at one end with a check nut and at the other end with a handle 106 and a locking pin 10? (Fig. 18) adapted to be dropped into a recess in the outer face of the adjacent side wall of the frame. Preferably, the rod 104 is connected with means for unlocking the button and fly holder bars 24, 38 so that, upon turning the rod 104, as many of the button and fly holders as may be desired may be conveniently removed from the ma chine. To this end, the slide 28 to which, as above stated, the button holder bars 24 are secured for horizontal reciprocating move ment, is formed in two parts pivotally connected to allow downward swinging movement of one of these parts relatively to the other. As shown, the rear part of the slide 28 near one end has integral therewith a depending lug 108 (Fig. 13), while the front part of the slide 28 has secured to its under side a lug 110 pivotally connected to the lug 108 by a screw 112 passing freely through the lug 108 and threaded into the lug 110. To efiect downward swinging movement of the front part of the slide 28 about its pivotal connection with the rear part of said slide, the rod 104 carries a split clamp 114- secured to the rod 104 for turning movement therewith by a screw 116 and having an upwardly. extending portion which carries a pin 118 arranged upon movement toward the slide 28 to enter a forked end 120 of the lug 110. Upon continued turning movement of the rod 104, the pin 118 swings the front part of the slide 28 downwardly far enough to clear the rolls 122 by which the button holder bars 24 are secured to the slide 28 for horizontal movement therewith. This permits the button holder bars 24 to be freely removed from the machine, after which the corresponding fly holder bars 88 may be similarly removed by lowering them until the rolls 124 by which the fly holder bars 88 are secured to the slide 40 have cleared the under face of that slide. To maintain the front part of the slide 28 normally in its raised position, the screw 112 has wound around it a spring 126 the rear end of which engages the under face of the rear part of the slide 28 and the front end of which engages the under face of the front part of the slide 28. The opposite end of the front part of the slide 28 is similarly pivotally mounted and normally spring supported, as shown in Fig. 2.

In order that the anvils 64 may be raised and lowered toward and from the work, the anvil bars 102 intermediate between their ends rest upon a cross bar 128 (Figs. 1 and 2) secured for vertical adjustment of the anvil bars 102 and anvils 64 by set and binding screws, one of which is shown at 130 (Fig. 2), to the cross bar 182 of a yoke 134 fulcrumed for swinging movement upwardly and 'dowmvardly to raise and lower the anvil bars 102 and anvils 64 on a shaft 136 extending transversely of the machine and supported in the machine frame. A tie rod 138 (Figs. 1 and 2) straddles the anvil bars 102 and secures them to the cross bar 128 for movement with the yoke 134. The yoke 134 is operated by a heavy toggle comprising links 140, 142 pivoted together at 143. The link 140 is pivoted to the yoke 134 at 144 (Fig. 2) and the link 142 is fixed at its lower end to a rock shaft 146 (Figs. 1 and 2) mounted in bearings in the machine frame and carrying fixed to it near its outer end a link 148 (Fig. 1) pivoted to an operating rod 150 pivotally supported at its rear end by a link 152 (Fig. 2) pivoted on the shaft 33 and carrying a roll 154 arranged to engage a cam 156 on the main shaft 80. In the normal positions of the parts, the toggle 140, 142 is broken, as shown in Fig. 2, and the anvils 64 are positioned below their work engaging position. Upon movement of the operating rod 150 to straighten the toggle 140, 142, the yoke 134 is moved tons into the button forks 2 and position and hold the buttons positioned in the said forks in line with the plungers 62. These jaws comprise an upper jaw 158 carried at the front end of a supporting bar 160 and a lower jaw 162 carried at the front end of a rod 164: pivoted at 166 to the bar 160 (Figs. 2, 1d and 15). The jaw supporting bar 160 passes through and is supported in the center guide 26 between the center button holder bar24 and the center anvil bar 102. The rear end of the bar 160 is slotted to receive a bent rod 168 (Figs. 2 and 14) having an upwardly extending front end 169, upon which the bar 160 is hung. A rearwardly extending rod 170, secured to the rod 168 in an offset position by a tie piece 172, slides in a bearing 1741 (Fig. 2)

1 carried on the shaft 136. The described construction permits ready detachment of the jaws 158, 162 from the machine by lifting the bar 160 from the upwardly extending part 169 of the bent rod 168 when permitted by prior removal of the button holder bars 24.

Conveniently, the button piece engaging jaws 158, 162 are arranged for movement with the fly holders 4 so that, as the fly holders are drawn backwardly to position the buttonholes in line with the plungers 62, the jaws 158, 162 are moved backwardly to position the buttons in the button holders 2 in line with the buttonholes and plungers 62. In order that the jaws 158, 162 may be thus operated with the fly holders 4, the tie piece 172is pivotally connected at 176 to a link 178 (Fig. 2) the rear end of which link is pivoted at 180 to the lever 43 which operates the fly holder bars 38.

To provide for closing the button piece gripping jaws 158, 162 in engagement with the button piece, in the illustrated construction, the lower jaw 162 is provided with spaced depending extensions 182 (Fig. 15) arranged'to straddle the center anvil bar 102 and to rest on the anvil bars 102 at either side of the center anvil bar. The said anvil bars 102 upon which the extensions 182 of the lower jaw 162 rest have secured to their top faces, by means of adjusting screws 18st and binding screws 186 (Figs. 2 and 3), cam blocks 188, upon which the extensions 182 of the lower jaw 162 ride, the construction being such that during the first part of the backward buttonhole positioning movement of the fly holders l, the said extensions of the lower jaw 162 are caused to ride upwardly upon the cam blocks 188 to close the jaws in engagement with the button piece, while on continued backward movement of the fly holders 4-, the button piece is drawn baclnvardly to aline the buttons with the Corresponding buttonholes and plungers 62 (Fig. at).

The upper jaw 158 preferably carries an abutment plate 190 (Fig. 14:) spaced from and secured to the jaw 158 by strips 192. In the introduction of the work into the machine, the eyes of the buttons are thrust against the front face of the abutment plate 190 and held there by the opera tor until the jaws 158, 162 close upon the button piece. Preferably, the lower jaw 162 comprises a spring bar 194 (Fig. 15) carrying at its ends transverse work engaging plates 196 having their upper and work ongaging faces roughened or corrugated to give them a sufliciently firm grip upon the work. The spring construction of the lower jaw 162 gives it a considerable adaptability to button piece stock of different thicknesses, while the above-mentioned screws 184: for efl'ecting vertical adjustment of the cam blocks 188 provide for determiningthe extent of closing movement of the jaws, thus further adapting them for work of diiferent thicknesses.

After the buttons and buttonholes have been brought into alinement with the plungers 62 through backward movement of the fly holders 4, as above described, the plungers 62 are lowered by downward movement of the head 92 and caused to enter the buttonholes. Thereafter the spreader blades 52 are swung downwardly out of the buttonholes and the fly holders 4 and spreaders 6 are withdrawn to an inoperative position in the rear of the plungers 62. Upon con tinued downward movement of the head 92 the plungers 62 are lowered into engagement with the crowns of the button heads and the anvils 64- are raised, through upward movement of the yoke 134 upon straightening of the toggle 140, 142 through the rod 150 and cam 156, into engagement with the lower side of the button piece in position to support the eyes of the buttons in opposition to the plungers 62. The button holders 2 are then withdrawn backwardly to an inoperative position. Thereafter, while the buttons are thus held against translation between the plungers 62 and anvils 6a and the buttonholes are held positioned in alinement with the heads of the buttons by the plungers 62, each buttonhole is disposed in buttoned relation to the corresponding button by buttonhole fly engaging means comprising for each set a pair the corresponding plunger sleeve 68.

of relatively movable buttoning members 200, 202, for coveuience herein usually termed tuckers and preferably made of spring material. These buttoning members 200, 202 are arranged to be moved with the plungers 62 upon movement of the head 92 to bring the plungers into engagement with the heads of the buttons and thereafter to have relative movements first independently of the head 92 and then with the head 92 to dispose first one and then the other side of each buttonhole in buttoned position.

Each tucker 200 is pinned at 204C and 206 (Fig. 16) to a plate 208 integral with or fixed to a rod 210 slidably mounted in a vertical slot 212 in a forward extension of The lower end of each tucker carrying rod 210 is cushioned against a spring 214: seated in an extension of the slot 212 and serving as a return spring to raise the said tucker 200 to its normal inoperative position when permitted. Each tucker 202 is pinned through a hole 216 (Fig. 18) to the outer face of the said extension of the sleeve 68 on the other side of the said sleeve and directly opposite the plate 208, each tucker 202, in consequence of its said mounting, being always movable with its sleeve 68 upon movement of the cross head 92.

For imparting to each tucker 200 a buttoning movement relatively to its sleeve 68 and the opposed tucker 202 while said parts remain stationary, the illustrated machine is provided with an auxiliary cross head 218 (Figs. 1 and 2) normally engaging the top faces of heads 220 on the upper ends of the rods 210, the heads 220 being integral with said rods or, as shown, in the form of split clamps pinned to said rods. To provide for reciprocation of the auxiliary cross head 218, the said cross head is carried at the front ends of two forwardly extending levers 222, 224, (Fig. 1), each of which is fulcrumed at 95 (Fig. and connected at its rear end to a forwardly extending arm of a bell crank 226 fulcrumed on the shaft 96 and having a single rearwardly extending arm 228 carrying a roll 230 in the path of a cam on the main shaft 30, the rear ends of the levers 222, 224: being slotted to receive blocks 233 on pivot pins 235 carried by the said forwarly extending arms of the bell crank 226.

In the operation of the machine, the tuclters 200 and 202, by reason of their above described mounting, are carried downwardly vith the plunger carrying sleeves 68 upon downward movement of the head 92 to bring the plungers 62 into engagement with the heads of the buttons. After the plunger-s have engaged the heads of the buttons and the anvils 6% have been moved upwardly so that the buttons are clamped between the plungers 62 and the anvils 64- and the fly holders 4 and button holders 2 have been moved backwardly into inoperative positions, a downward movement of the auxiliary head 218 is effected while the main head 92 remains stationary. During this clownward movement of the auxiliary head 218, the tuckers 200 are forced downwardly, relatively to their carrying sleeves 68 and the tuckers 202, to force one side of each buttonhole over the adjacent portion of the edge of the corresponding button head and under the button head in buttoned position by engagement of the said tuckers 200 with the buttonhole edge binding stitches on the top face of the buttonhole fly. Thereafter, a further donniward movement of the main head 92 is efiected. During this movement of the head 92, the plungers 62 remain sta tionary by reason of their engagement with the heads of the buttons the eyes of which are rigidly upheld by the anvils 64L, while the plunger carrying sleeves 68 move downwardly against the tension of the springs 76. This downward movement of the sleeves 68 carries the tuckers 202 downwardly relatively to the tuckers 200 to force the other side of each buttonhole over the edge of the corresponding button head and dispose it in buttoned relation under the button head by engagement with the buttonhole edge binding stitches on the top face of the buttonhole fly at that side of the buttonhole, in the same manner that the first side of each buttonhole was carried into buttoned position by the tuckers 200, thus completing the buttoning of each button.

To facilitate the buttoning action of the tucker-s 200 and 202, they are preferably formed at their lower ends (as best shown in Figs. 18 to 20) to conform substantially to the contour of the heads of the buttons and to tuck the stock on the two sides of each buttonhole under the head of the adjacent button and then to crowd the said stock snugly against the eye of the button, each of the tuckers 200, 202 being provided with inturned ends indicated at 2% (Figs. 18 and 19) and these inturned ends and the portions of the tuckers adjacent thereto being curved to conform substantially to the curvature of the edge of a button head, as clearly 115 shown in Fig. 19.

To facilitate forcing the sides of each buttonhole over the edge of the corresponding button head, each of the illustrated tuckers 200, 202 is provided with an inwardly ex- 120 tending projection providing a cam face 236 (Fig. 19) arranged to lie in a slot 238 (Fig.

16) formed in the adjacent face of the corresponding plunger 62, each slot 238 having a raised hump indicated at 240 (Fig. 16) 125 upon which the cam face 236 of the adjacent tucker 200,202 rides during the first part of the buttoning movement of that tucker, with the result that each tucker is thereby given a preliminary outward movement to- 130 entrance of the spurs into the button holes, each spur 2&2 is preferably wedge shaped'with a stralght lnslde face and an inclined outside face, as clearly shown in Figs. 19 and 20.

To lessen the strain upon the tuckers 200 .and 202'during the operation thereof, preferably each tucker is made in two parts, the shank part having a bifurcated lower end 244 formed to receive a tongue 2&6 projecting upwardly from the work engaging part (Fig. 18), the shank part and the work engaging part of each tucker being hinged together by a pivot pin 2&8 passing through the bifurcated end 2% of the shank part and the tongue 24-6 of the work engaging part. A spring 250 pinned at 252 Fig. 3) to a part of the associated plunger carrying sleeve 68 has an arm overlying the work engaging part of each tucker 200, 202, the springs 250 pressing the work engaging parts of the tuckers of each pair inwardly toward each other and the intermediate plunger 62.

After the completion of the buttoning operations, the heads 92 and 218 are raised and the anvil yoke 13% is swung downwardly to release the work from the plungers, tuckers and anvils, the parts being finally restored to their initial positions.

In addition to the adjustments hereinbefore explained, the illustrated machine has provision for making a number of other adjustments of the, operating instrumentalities.

To provide for adjusting the operating instrumentalities of the machine for operating upon differently spaced buttons and buttonholes, the several sets, except the center set, are arranged for simultaneous movement from and toward each other. To this end each of the guides 26, except the center guide 26, has a projection 251 standing in a slot extending transversely of the machine ina horizontal tie plate 253 (Fig. 11) fixed at either end to the machine frame, the said tie plate permitting sliding movement of the movable guides 26 along said slot and at the same time securing the guides 26 against movement lengthwise of the ma chine by engagement of said projections on the guides 26 with the walls of the slot in the tie plate. F or elfecting such sliding movement of themovable guides 26, the said guides are connected by a system of toggles comprising a series of links 25 1 (Figs. 2 and 11) pivotally connected at their outer ends to cap plates 255 overlapping the tie plate and pivoted at their inner ends to a lever 256 constituting a common central toggle link and fulcrumed on the fixed center guide 21", the toggle links 25% extending reversely on opposite sides of the center link 256. The common center .link 256 at its forward end is connected to an arm 258 of a sliding controller 260 by a pin and slot connection. The controller 260 is operated by a bell crank 262 fulcrumed to the machine frame at 26L One arm of the bell crank 262 carries a horizontally disposed segmental gear engaging a companion gear carried by an arm 266 of a bell crank 26S fulcrunied on the machine frame at 270 and operated by a treadle rod indicated at 272. The controller 260 is connected with the holders 90 by a system of toggles like the toggles above described for connecting the controller with the movable guides 26 so that, upon movement of the treadle 272 and consequent movement of the controller 260. the several movable sets are moved as units to position their instrumentalities away from or toward each other to vary the spacing of the sets.

To provide for adjusting the plungers 62 and associated buttoning members 200, 262 according to the line or curve of the outer edge of the buttonhole fly and consequently the line or curve of the buttons and buttonholes, each of the holders 90, except the center holder, is pivoted at 2741- to the head 92 for swinging movement about the said pivot 274, the lower portions of each of the holders 90 being provided with screws 276, 27 7 whereby the holders 90 may be adjusted about their said pivots and se cured in adjusted positions. A correspond ing adjustment of the button and fly holders may be effected by moving the slide bars 24 and 38 lengthwise of the machine relatively to their connections 122 and 124 with the slides 28 and 40, a like adjustment of the anvils 64 being provided for as above stated, by reason of their described adjustable mounting in the slots 105 in the front ends of the anvil bars 102.

To adjust the plungers 62 and associated buttoning members 200, 202 for buttonholes set in different angular positions, each sleeve 68 is provided near its top with an annular groove 278 (Fig. 16) adapted to be engaged by a screw 280 threaded through the sleeve 68.

The operation of the machine may be summarized as follows: The work is introduced into the machine as shown in Fig. 3 by placing the button eyes between the arms of the button receiving forks 2 and resting the heads of the buttons upon the said forks 2, the end buttons being inserted between the spring fingers 1A- and the eyes of the buttons being pushed against the abutment plate 190. The buttonhole fly is then carried over and rested upon the fly holders 4, the buttonhole spreader blades 52 projecting upwardly through the buttonholes.

During the first part of the operation of the machine, the fly holders 4: are moved backwardly toward the machine to bring the buttonholes in alinement with the plungers 62 (Fig. 4:), the spreader arms 46 being forced apart to cause the spreader blades 52 to open the buttonholes and hold them open for the passage therethrough of the plungers 62. This positioning movement of the fly holders 4 also pulls the jaws 158, 162 backwardly, causing the jaws to be closed to seize the button piece and then to impart to it apositioning movement to draw the buttons into the forks in alinement with the buttonholes and plungers 62. Thereafter, the plungers 62 are lowered by downward movement of the head 92 to cause the said plungers to enter the buttonholes. After the plungers 62 have entered the buttonholes, further backward movement of the fly holders 4 while the button holders 2 are held stationary, causes the buttonhole spreaders 6 to be swung downwardly to Withdraw the spreader blades 52 from the buttonholes, still further backward movement of the fly holders A bringing the fly holders 4 and spreaders 6 into inoperative positions. Continued downward movement of the head 92 after the plunger-s 62 have entered the buttonholes lowers the plungers into engagement with the crowns of the button heads, the anvils 64 being moved upwardly to support the eves of the buttons from below (Fig. 5). The button holders 2 are then withdrawn backwardly to an in operative position whereupon downward movement of the auxiliary head 218 operates the tuckers 200 to carry one side of each buttonhole over the adjacent portion of the edge of the corresponding button head and dispose it in buttoned relation under the head of the button, the first part of this downward movement of the tuckers 200 carrying them into engagement with the buttonhole edge binding stitches on the top face of the buttonhole fly. Thereafter upon engagement of the cam faces 236 on the said tuckers with the cooperating cam faces 240 on the plunger-s 62, the tuchers 200 are moved outwardly to carry the sides of the buttonholes being operated upon to the peripheral edges of the button heads, the spurs 242 depending from the tuckers maintaining engagement of the said tuckers with the said edge binding stitches during this preliminary movement. Upon further movement of the auxiliary head 218, the tuckers 200 force the sides of the buttonh oles over the edges of the button heads, the inturned lip portions 23% tucking the stock snugly against the eyes of the buttons. There-after, upon movement of the head 92, the tuckers 202 are operated similarly to engage the second side of each buttonhole at its edge, to carry that side of each buttonhole outwardly to the peripheral edge of the button head, and then to crowd it over the edge of the head and dispose it in buttoned position under the head of the button. After the completion of the buttoning operations, the parts are restored to normal positions, the buttoned work being thereby released from the machine.
